"Jotto is a word-guessing game more akin to code-breaking games such as Mastermind than to the comparatively simple-minded Hangman.
In traditional face-to-face competition, two players alternate in trying to guess the opponent's hidden word, and the game ends when one player succeeds. In this computer version, only the computer has a hidden word, and you have 15 turns to guess it.
The hidden word consists of five letters with none repeated (e.g. ""wades"" is valid but ""waded"" is not). Your guesses must also contain five different letters, and to play fairly you must use only English words. In the registered verion, the program will warn you before accepting a word that is not in its wordlist. The shareware version has no way of knowing if you have entered a word that does not exist.
To submit a guess, simply type it in the edit box (in upper or lower case) and press Enter.
After each guess, the computer shows your word with a figure beside it. This figure is the number of letters in the guess that match letters in the hidden word. Position is not relevant to the count. For example, if the hidden word was ""great"" and you guessed ""grate"", the count would be 5. Note that in this case you still haven't won; you have to guess the hidden word with the letters in the correct order.
To give up, choose New Game from the File menu. The hidden word for the last game will be revealed."
